The present specification relates to a method by which a first terminal performs a session handover in a wireless communication system, wherein the method for performing a session handover can comprise the steps of: forming an ASP session with a second terminal by a first connecting method; transmitting a session handover request to the second terminal; receiving a session handover response from the second terminal; and transmitting a session handover confirm to the second terminal, wherein, when the session handover response is received from the second terminal, the formed ASP session can be handed over by a second connecting method.

Communication network architectures, systems and methods for supporting a network of mobile nodes. As a non-limiting example, various aspects of this disclosure provide detail of a method, a system, and a non-transitory storage medium for managing and triggering handover of a mobile network node in a network of moving things comprising a plurality of network nodes.

The present disclosure relates to a pre-5.sup.th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4.sup.th-Generation (4G) communication system such as Long Term Evolution (LTE). According to embodiments, an access and mobility management function (AMF) comprises at least one transceiver; and at least one processor, wherein the at least one processor is configured to receive, a mobility management entity (MME) for an evolved node B (eNB), a message associated with a handover required message for an inter-system handover from an evolved packet system (EPS) to 5G system (5GS) with a secondary gNB (SgNB) used as a target next generation node B (gNB), wherein the SgNB and the target gNB are co-located and the eNB is associated with the SgNB in a dual connectivity; transmit, to the target gNB, a handover request message for the inter-system handover from the EPS to 5GS with the SgNB used as the target gNB; and receive, from the target gNB, an acknowledge of the handover request message. The handover required message includes an SgNB user equipment (UE) X2 application protocol ID (SgNB UE X2AP ID) for identifying a UE over X2 interface in the SgNB. The handover request message includes the SgNB UE X2AP ID, and the SgNB UE X2AP ID is allocated at the SgNB.

A mobility management network element in a visited network performs a method in a home-routed roaming operation to facilitate a switching of a terminal in a session to the visited network. The mobility management network element obtains single network slice selection assistance information (S-NSSAI) for a home network of the terminal corresponding to the session of the terminal. The mobility management network element also obtains S-NSSAI for the visited network corresponding to the session of the terminal, according to a mapping relationship between the S-NSSAI for the home network and the S-NSSAI for the visited network. The mobility management network element then sends the S-NSSAI for the visited network to an access device of the terminal in the visited network, for the access device to process the session.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a master node (MN) may receive information indicating one or more candidate target secondary nodes (SNs) for a multi radio access technology dual connectivity (MR-DC) handover of a user equipment (UE), wherein the information indicates that the one or more candidate target SNs are associated with direct forwarding paths with a source radio access network (RAN) node of the UE; select a target SN from the one or more candidate target SNs based at least in part on the received information; and perform the MR-DC handover of the UE, wherein the selected target SN is different than the source RAN node of the UE, and wherein a configuration of the MR-DC handover is based at least in part on a direct forwarding path between the selected target SN and the source RAN node.

Systems and methods are provided for optimizing use of wireless communication technologies for a UE. The method can include determining that the UE has established a first wireless communication link to a first node that can use both a first and a second wireless communication protocol, then determining whether, prior to connecting to the first node, the UE was previously connected to a second node that only utilizes the first wireless communication protocol (e.g., standalone 5G). If the UE was previously connected to the second node and moved to the first node because of fallback or handover procedures, a second communication link is established between the UE and the second node without analyzing single information corresponding to the UE.

Techniques that facilitate mobile device self-optimizing technology selection thresholds for a wireless communication system are provided. In one example, a method comprises: generating, at a first time, first information in a repository of information specific to and stored at the apparatus, wherein the first information comprises an identifier for a first access point device and a determined acceptable signal strength usable to obtain an acceptable jitter value between the apparatus and the first access point device; and initiating a defined type of communication via the first access point device, at a second time, based on a first determination that a detected signal strength at a third time satisfies a defined condition relative to the acceptable signal strength, wherein the second time is after the first time and wherein the third time is between the first time and the second time.

Managing data resource utilization in a wireless network environment comprising a first data network and a second data network is described herein. The described management infrastructure and method incorporates monitoring data usage of a wireless network subscriber over the first data network, determining that the data usage over the first data network meets a specified threshold, and, in response to the determination that usage has reached the specified threshold, administratively disconnecting the wireless network subscriber from the first data network so as to cause a data session of the wireless network subscriber to be reassigned to the second data network.

According to one embodiment, a method for establishing a communication is described comprising performing, over a first mobile radio communication network, a call control protocol message exchange indicating that a communication session establishment between a first communication device and a second communication device is intended; initiating a fallback by the first communication device from the first mobile radio communication network to a second mobile radio communication network, in reaction to a specific call control message of the call control protocol message exchange; performing the fallback and establishing the communication session between the first communication device and the second communication device via the second mobile radio communication network.

In accordance an embodiment of the disclosure, a method performed by a user equipment (UE) in a wireless communication system is provided. The method may comprise: identifying an inter-system change from a first mode to a second mode, transferring a data session established in the first mode to the second mode from the first mode, determining whether the UE and a network entity in the second mode support a header compression, and initiating, based on a result of the identifying, a procedure for negotiating a header compression configuration in the transferred data session, wherein the first mode is one of N1 an mode or an S1 mode, and the second mode is the other of the N1 mode or the S1 mode.
